Search column headers and insert new column using Excel VBA - excel

Question

I have a spreadsheet that is updated regularly. Therefore the column header positions change regularly. eg. today "Username" is column K, but tomorrow "Username" might be column L. I need to add a new column to the right of "Username" but where it changes I cannot refer to as cell/column reference.
So far I have:
Dim rngUsernameHeader As Range
Dim rngHeaders As Range
Set rngHeaders = Range("1:1") 'Looks in entire first row.
Set rngUsernameHeader = rngHeaders.Find("Username")
When I go to add a new column to the right of it, I'm selecting that row but it's going back to cell/column references...
Columns("K:K").Select
Selection.Insert Shift:=xlToRight
Range("K1").Select
ActiveCell.FormulaR1C1 = "Role"
How can I perform this step with a macro?
edit: I think need to give that Column a header name and begin populating the row with data - each time I do begins the cell references which I want to avoid wherever possible.
Many thanks in advance.

Answer 1

How about:
Sub qwerty()
Dim rngUsernameHeader As Range
Dim rngHeaders As Range
Set rngHeaders = Range("1:1") 'Looks in entire first row.
Set rngUsernameHeader = rngHeaders.Find(what:="Username", After:=Cells(1, 1))
rngUsernameHeader.Offset(0, 1).EntireColumn.Insert
rngUsernameHeader.Offset(0, 1).Value = "role"
End Sub

Answer 2

Sub AddColumn
Dim cl as Range
For each cl in Range("1:1")
If cl = "username" Then
cl.EntireColumn.Insert Shift:= xlToRight
End If
cl.Offset(0, 1) = "role"
Next cl
End Sub

Something like this should work. The idea is that you locate the column and then you insert to the right. That is why you have the +1 in the TestMe. The function l_locate_value_col returns the column, where it has found the value. If you want, you may change the optional parameter l_row, depending on which row do you want to look for.
Option Explicit
Public Sub TestMe()
Dim lngColumn As Long
lngColumn = l_locate_value_col("Username", ActiveSheet)
Cells(1, lngColumn + 1).EntireColumn.Insert
End Sub
Public Function l_locate_value_col(target As String, _
ByRef target_sheet As Worksheet, _
Optional l_row As Long = 1)
Dim cell_to_find As Range
Dim r_local_range As Range
Dim my_cell As Range
Set r_local_range = target_sheet.Range(target_sheet.Cells(l_row, 1), target_sheet.Cells(l_row, Columns.Count))
For Each my_cell In r_local_range
If target = Trim(my_cell) Then
l_locate_value_col = my_cell.Column
Exit Function
End If
Next my_cell
l_locate_value_col = -1
End Function

You could name your range:
Sub Test()
Dim rngUsernameHeader As Range
'UserName is in column F at the moment.
Set rngUsernameHeader = Range("UserName")
Debug.Print rngUsernameHeader.Address 'Returns $F$1
ThisWorkbook.Worksheets("Sheet2").Range("E:E").Insert Shift:=xlToRight
Debug.Print rngUsernameHeader.Address 'Returns $G$1
End Sub
Edit:
Have rewritten so it inserts a column after your named column and returns that reference:
Sub Test()
Dim rngUsernameHeader As Range
Dim rngMyNewColumn As Range
Set rngUsernameHeader = Range("UserName")
rngUsernameHeader.Offset(, 1).Insert Shift:=xlToRight
'You'll need to check the named range doesn't exist first.
ThisWorkbook.Names.Add Name:="MyNewRange", _
RefersTo:="='" & rngUsernameHeader.Parent.Name & "'!" & _
rngUsernameHeader.Offset(, 1).Address
Set rngMyNewColumn = Range("MyNewRange")
MsgBox rngMyNewColumn.Address
End Sub
